Shop 4" OD direct thermal labels for shipping, barcode printing, inventory, product identification, warehouse, retail, logistics, and other everyday business labeling applications. These blank white labels feature top-coated direct thermal face stock designed for reliable thermal printing without the need for ink, toner, or a thermal transfer ribbon.
Our 4" OD direct thermal label rolls are wound on 1" ID cores and feature permanent clear adhesive with the die cut waste removed. The compact 4" outside diameter makes these rolls a convenient choice for compatible direct thermal label and barcode printers designed to accept 1" core rolls.
Choose from a wide selection of label sizes, including popular 4 x 6 direct thermal labels for shipping and barcode applications, along with 4 x 8, 4 x 4, 4 x 3, 4 x 2, 3 x 3, 3 x 2, 3 x 1, and additional sizes for inventory, product identification, warehouse, retail, and general-purpose labeling.
Direct thermal labels print using heat-sensitive label material and do not require a thermal transfer ribbon. Always verify your printer's supported label width, roll diameter, core size, and media requirements before ordering.
